The battery is on the right side behind the fuse box. You need a metric set to undo the 3 screws. Theres one that attaches to the body, one to the bar that goes along the top, and theres one on the left side below the vacuum hose and air induction. After you've taken out those three, you should lift the whole thing out(battery and shroud) together. It's hard to take the shroud off before you lift the battery out. After that, you have to pry the shoud off the battery. The two terminals in the back make it hard. Then just go to any auto parts store and they'll give you a new one.

I have the same problem with my 2004 HD Sierra. I found that the "MBEC" 50 amp fuse in the under hood fuse box had blown. Replaced that and it works now. This has happened twice in 2 years.

It is located under the hood in the larger of the 2 AC lines, this large line is the low pressure line, also check on the round can the low side line connects to as it can be on that as well, that part is called the Accumulator/reciever drier

try turning up the idle ajustment screw also have alternator checked, another solution would be to have your car tuned up weak spark from your coil worn plugs wires etc. not enough power is being produced

If it does it when idling I would suspect an IAC motor (Idle Air Control). If it is opening too slowly the added air the motor needs will not be supplied fast enough and the engine will kill.
It could be other things also but this is where I would start.
